The first option is the correct answer
The answer is positive because the slope formula is y2 - y1/x2 - x1
By insterting our beautiful numbers we get the equation of: 5 - 3/4 - (-2)
That equals 2/6, which we can then reduce to 1/3. 1/3 is indeed positive. (I know I answered late, but I hope I helped!)

Answer:
Option b: (-0.3, -7)
Step-by-step explanation:
If we have two points v = (x₁, y₁) and w = (x₂, y₂)
The vector that connects these two points and starts in point v, is written as:
vector = w - v = (x₁, y₁) - (x₂, y₂) = (x₂ - x₁, y₂ - y₁)
In this case, we want to find the vector that goes from (-3.7,2) to (-4, -5).
Then we will have:
vector = (-4, -5) - (-3.7,2) = (-4 - (-3.7), -5 - 2)
vector = (-0.3, -7)
Then the correct option is b.
Answer:
x = -5 or x= 2
Step-by-step explanation:
|-4x-6| = 14
There are two solutions, one positive and one negative
-4x-6 = 14 -4x-6 = -14
Add 6 to each side
-4x-6+6 = 14+6 -4x-6+6 = -14+6
-4x = 20 -4x = -8
Divide by -4
-4x/-4 = 20/-4 -4x/-4 = -8/-4
x = -5 x = 2
